Journal ArticleDOI
Validity of spirometric testing in a general practice population of patients with chronic obstructive pulmonary disease (COPD).
Tjard Schermer,J.E. Jacobs,Niels H. Chavannes,Joliet Hartman,Hans Th.M. Folgering,Ben Bottema,C. van Weel +6 more
TL;DR: Relevant spirometric indices measured by trained general practice staff were marginally but statistically significantly higher than those measured in pulmonary function laboratories.
Journal ArticleDOI
Effects of written action plan adherence on COPD exacerbation recovery
Erik Bischoff,Dina H Hamd,Maria Sedeno,Andrea Benedetti,Tjard Schermer,Sarah Bernard,François Maltais,Jean Bourbeau +7 more
TL;DR: This study shows that adherence to a written action plan is associated with a reduction in exacerbation recovery time by prompt treatment, and knowing the factors that are associated with proper and prompt utilisation of an action plan permits healthcare professionals to better focus their self-management support on appropriate patients.
Journal ArticleDOI
Primary care spirometry.
Eric Derom,C. van Weel,Giuseppe Liistro,Johan Buffels,Tjard Schermer,E Lammers,Emiel F.M. Wouters,Marc Decramer +7 more
TL;DR: Softening the stringent ATS/ERS criteria could enhance the acceptability rates of spirometry when used in a general practice, and the implications of potential simplifications on the quality of the data and clinical decision making remain to be investigated.
Journal ArticleDOI
Comprehensive self management and routine monitoring in chronic obstructive pulmonary disease patients in general practice: randomised controlled trial
Erik Bischoff,Reinier Akkermans,Jean Bourbeau,Chris van Weel,Jan H. Vercoulen,Tjard Schermer +5 more
TL;DR: In this paper, the authors assess the long term effects of two different modes of disease management (comprehensive self management and routine monitoring) on quality of life (primary objective), frequency and patients’ management of exacerbations, and self efficacy (secondary objectives) in patients with chronic obstructive pulmonary disease (COPD) in general practice.
Journal ArticleDOI
Current clinical guideline definitions of airflow obstruction and COPD overdiagnosis in primary care
Tjard Schermer,Ivo Smeele,Bart Thoonen,Annelies Lucas,Joke Grootens,T. J. van Boxem,Yvonne F. Heijdra,C. van Weel +7 more
TL;DR: The aim of the present study was to establish the agreement between two recommended definitions of airflow obstruction in symptomatic adults referred for spirometry by their general practitioner, and investigate how rates of breeze obstruction change when pre-bronchodilator instead of post-bronschodillator spirometry is performed.
